  Synthesis and Biological Evaluation of Novel 1-Deoxy-1-[6-[((hetero)arylcarbonyl)hydrazino]- 9H-purin-9-yl]-N-ethyl-β-d-ribofuranuronamide Derivatives as Useful Templates for the Development of A_2B Adenosine Receptor Agonists

  摘要：

  The lack of molecules endowed with selective and potent agonistic activity toward the hA(2B) adenosine receptors has limited the studies on this pharmacological target and consequently the evaluation of its therapeutic potential. We report the design and the synthesis of the first potent (EC50 in the nanomolar range) and selective hA(2B) adenosine receptor agonists consisting of 1-deoxy-1-[6-[((hetero)arylcarbonyl)hydrazino]-9H-purin-9-yl]-N-ethyl-beta-D-ribofuranuronamide derivatives. The concurrent effect of 6-substitution of the purine nucleus with a ((hetero)arylcarbonyl)hydrazino function and a 2-chloro substitution has been investigated in such NECA derivatives.

  previous paper, we have disclosed a practical synthesis of 1-aryl-3H-pyrrolo[2,1-d][1,2,5]triazepin-4(5H)-ones. Now, these compounds have been used as the starting materials for the synthesis of three new ring systems, pyrrolotriazepines condensed with an imidazole, a triazole, or a tetrazole ring. The newly synthesized compounds are structurally closely related to tricyclic derivatives known from the literature

  strategy suitable for the quick preparation of a library of structurally diverse 1,2,4-triazoles in a one-pot setting. The key steps include the formation of thioureas followed by S-alkylation using 1,3-propane sultone and consecutive ring closure leading to the desired 1,2,4-triazoles. Parallel synthesis yields thousands of 1,2,4-triazoles in a cost- and time-efficient manner from commercially available
